Has any tried the Leupold LX base and ring scope mounting system on their big bore riles?

Leupold clams this system can:
- The latest in super high-end rapid release/remount systems.

- Incredible zero retention, to retain its point of impact even after being removed and replaced.

- Uses a locking lever to cam into place more quickly and securely than ever.

- Ideal for dangerous game situations, when the need to use iron sights can come at a moment’s notice.
Exceptional system for traveling, you can remove and replace it quickly.

Here's a link to the Leupold web page:http://www.leupold.com/hunting-and-shooting/products/mounting-systems-and-accessories/mounting-systems/lx-mounting-system/

Sure do like mine. Installed on a Kimber Caprivi 375H&H model 8400 long action. Works as advertised.
